Fig. 1(b) is a schematic structural view of an enlarged view of the region a in fig. 1 (a). In this embodiment, the screen assembly 10 includes a backlight module 100, a display panel 200, a cover plate 300 and a camera module 400; the cover plate 300, the display panel 200 and the backlight module 100 are sequentially stacked, the backlight module 100 is provided with an installation through hole 100A, and the installation through hole 100A is used for accommodating the camera module 400; a first ink layer 510 is disposed between the backlight module 100 and the display panel 200; a second ink layer 520 is disposed between the display panel 200 and the cover plate 300; the first ink layer 510 and the second ink layer 520 cooperate with each other to block the light leakage from the display panel 200 and the backlight module 100 toward the camera module 400.

The display panel 200 is a liquid crystal display panel. The camera module 400 is a front camera.

The first ink layer 510 and the second ink layer 520 are used for blocking the transmission of light.

Optionally, in this embodiment, the first ink layer 510 is provided with a first through hole 510A, and the camera module 400 partially penetrates through the first through hole 510A and is attached to the edge of the first through hole 510A. Specifically, when the edge of the first through hole 510A of the first ink layer 510 is attached to the camera module 400, the light leakage of the backlight module 100 toward the camera module 400 can be sufficiently blocked.

Optionally, the second ink layer 520 is provided with a second through hole 520A, and the second through hole 520A is opposite to the first through hole 510A. Further, the aperture h1 of the second via 520A is larger than the aperture h2 of the first via 510A.

Specifically, because the camera module 400 has a symmetrical structure, when the second through hole 520A is aligned with the first through hole 510A, on one hand, it can be ensured that the second through hole 520A and the first through hole 510A do not shield external light rays from entering the camera module 400, so that the camera module 400 has a better shooting visual angle, and on the other hand, the first ink layer 510 and the second ink layer 520 can be made smaller, which is beneficial to reducing the proportion of the first ink layer 510 and the second ink layer 520 occupying the display panel 200, and is further beneficial to improving the screen occupation ratio of the screen assembly 10.

Furthermore, since the viewing angle range of the camera module 400 is a cone structure and is divergent from the camera module 400 toward a direction away from the display panel 200, when the aperture of the second through hole 520A is larger than the aperture of the first through hole 510A, it can be ensured that the second ink layer 520 does not block external light from entering the camera module 400, meanwhile, the second ink layer 520 can also reduce the light leakage of the display panel 200 toward the camera module 400, and the second ink layer 520 is also used for blocking metal wires in the display panel 200, on one hand, the camera module 400 can have a better shooting viewing angle range, on the other hand, the metal wires in the display panel 200 are blocked, when a user looks from the outside of the screen assembly 10, the internal structure of the display panel 200 cannot be seen, and therefore, the uniformity of the appearance of the screen assembly 10 is improved.
